LOUIS A. CASGRAIN, OF BEVERLY, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY. OF PATERSON,

JERSEY.

1910. Serial to all whom it may concern: Be it known that I, LOUIS A. OASGRAIN, a-eitizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Iniprovements in Gages, of which the following description, in connection with the accompanying drawings, is m specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to work gages. In ,its illustrated preferred embodiment, the invention is shown as applied to a ma-i chine for inserting fastcnings into the heels; and soles of boots and shoes, the principal function of Work gages in machines of thisi type being to determine the distance from the edge of a heel or sole at which the fastening is to beinserted, thus causing the fastenings which are successively inserted to form a row parallel to the edge of the Work, I

It is frequently desired, especially when doing ornamental work, to insert two or more parallel rows of fastenings, and a general object of the present invention is to provide an improved gage which can readily be set to determi ne,rows of fastenings ditler-' ently-spaced from the edge of the work.

-More specifically, the invention aims to provide an improved two-row or two-wa' gage which may readily be adjusted to di erent ranges of movement between the extreme' limits of its movement and which may readily be moved from a determined first row position into a determined second row position, or vice versa, without especial attention on the part of the operator.

In the accompanying drawings,-Figure 1 is a side elevation of the gage and its earrying arm, the parts being shown in operative position in a machine for inserting fastenings; Fig. 2 is a perspective view of the gage and its carrying arm removed from the machine; Fig. 3 is a detail perspective of means for moving the gage.

For the purposes of this de cription the gage herein shown may be considered as employed with a machine of the type disclosed in .m co-pending application Ser. No. 694,381, filed October 24, 1898, for Letters Patent for improvements in nailing machines the present application constituting Specification of Letters latent.

NEW JERSEY, A CORPORATION OF NEW (GAGE.

Patented Oot.8,1'912.

694,381. Divided and this applicatipn filed May 20, No. 562,498.

it may be considered as employed with ma ehines of other types, for example, with the machine shown in United States Letters Patent 786,190, granted March 28, 1905.

Referrin to the drawings, the gage and the mechanism for moving it are preferably supported by an arm 2 pivoted upon a stud 4 screwed into the machine head, the hub 6 of the arm being provided with a flattened portion 8 which is engaged by a springpressed plunger 10 to maintain the arm in its elevated position, provision being thus made for moving the arm into a position to carry the gage out of operative relation to the inserting n'lechanism, such position of the arm being shown in dotted lines in Fig. 1. The end of the arm rg-mote from its hub is enlarged and provided with a bearing 12 for crank shaft 14- which carries a crank pin 16 by which longitudinal movement of ing ecccntrically positioned upon the shaft 14 and being threaded into the end of said shaft. The gage 18 is upturned at its rear end, said upturned end being inturned at its upper edge at 20 to enter and be guided by a horizontal groove 'l'ori'ncd in a plane vertical face of the arm said face being formed upon one end of the bearing 12. The crank pin it enters a vertical slot 24. in the upturned end of the gage 18 and thus transmits movement to the gage as it turns about the axis of the shaft 14. A spring .26 on the c 'ank pin 16, hearing against the upturned end of the gage 1S and hooked over the sides of said upturned end, presses the inturncd part of the gage into the groove 92 and at the same time provides friction by which too easy turning of the shaft 14 is prevented.

The shaft H is provided at its end opposite to that which carries the crank pin it) with a flange 28 which is held against the other end of the bearing 12 by'the actionvof the spring 26. handle 30 for turning the shaft 11 is clamped upon said shaft by means of a set screw t"! threaded into the end of said shaft, the handle being free to be adjusted into different angular relations to said shaft. if desired, the flange 28 may be replaced by a washer to be clamped to the sha H H together with the handle 30 and the stop plate hereinafter described.

a division of said (op -riding application, or

the gage 18 is ctl'ected, the crank pin it bci seen that the extreme limits of movement of pin lfiengagmg the bottom of thisslot at each of the limits of movement of the-gage in the illustrated construction. Thiseccentricity is preferably made great enough to cover the extreme range of movement'of the gage 18 which wouldbe-desired withthe dif-..: ferent classes of work which the machine is designed to handle. It is, however, very rarely desirable to space two rows of fastenings the distance apart provided by the extreme range of movement of the gage l8, and means is therefore provided for determining a range of movement less than that of 'the extreme movement provided by the" eccentricity of the crank pin 16 to the shaft 14. The illustrated means comprises a. notched stop plate' 34 clamped between the;

hub 36 of the handle 30 and the flange 28f upon the shaft 14, said stop plate being provided with two stops 3'8v and 4O angularly= spaced with respect to the axis of rotation of? the shaft 14 to determine two limits ofmovement of the gage 18 as they cooperate with a fixed stop pin 42 upon the arm 2. The stop plate 34 is adjustable about the set screw 32 into different angular relations to-the shaft 14 and also into different angular relations to the handle30. The first row and second row positions of the gage can therefore be adjusted at the will of the operator.- When the desired first row and second row positions-of the gage have been determined, the stop plate 34 is clamped to the shaft 14 and the operator thereafter merely turns the handle 30 ,to the two limits of its movement determined by the engagement of the respective stops 38 and 40 with the fixed :pin42, such movement of the handle efiectmgthe; movementof the gage from first 'rowfto sec-' gondrowposition, or vice versa.

.Iti-Willbe seen from an inspection of the drawings that the stop plate 34 may be so adjuste that only one of the stops'38, 40

will engage the fixed pin 42 when the gage is moved from its first row position to its second row position and back again, and that thus by causing one of the stops to'coopen ate with one of the extreme limits of movement of the gage a distance between the first and second rows less than that determined by the angular spacing of the stops 38 and 40 may be provided. It will be seen further that the stop plate 34 may be. adjusted to cooperate in this way with either of the extreme limits of movement of the gage. The operation of the gage in'this case wiltbe the same as when both stops are used, ex-- cept that one limit of movement of the handle 30 Will be determined by the engagement of the crank pin 16 with the bottom of the slot 24. I

When it is desired to provide, within the extreme limits of movement of the ga e 18, a spacing between the first and secon rows .difi'erent from that provided by the angular spacingof the stops 38 and 40, a'stop plate having a different angular spacing of these stops may be substituted for. the stop plate 34.
